galaxy dx 95t2 mods?

[preacherman]

If that radio is swinging to 180+ w on AM...it's already doing good.
I wouldn't remove the limiter if you plan on using it on ssb...unless
you remember to lower the mic gain. It also might start squealing
and "will" bleed more channels if you remove the limiter...but it's your
radio.

If you want more swing, there are a few mods you can do...but it won't
take it from "OK" to "dang".

My suggestion would be to take it to someone qaulified who has a scope and various other things a real shop should have and have them do a full alignment and set the amc and alc for proper and clean modulation.... The radio will swing just fine without any stupid mods or so called swing kits added.... Removing the limiter isn't going to make the radio sound any better, it will only show you fake watts on a meter and a bunch of splatter into other bands.... As previously stated by Preacherman, it's your radio do as you please....

[Red Warrior]

I cranked the AMC up all the way and it really woke the audio up. Doesn't sound distorted or overmodulated surprisingly.

Can a top gun modulator/speech compressor be added to this radio?

You seem intent on making this radio into a splatter monster regardless of advise to the contrary. The only thing this radio needs is a bigger speaker. The manufacturer replaced the 4" speaker with a 3" speaker when they added the heat sink. Makes the receive on the radio sound tinny. Use an external speaker and leave the shiny little capacitors alone.

[freightliner06]

Yep, that's what I want. A loud, splatter-box radio. Hopefully I live near you so I can ruin your day with it.

Anyone have any info on the NPC-RC for this radio?

Honestly, I would advise against the NPC-RC mod for this radio as it does not need it and the radio will swing just fine without it.... 2 watts swinging 180 looks like garbage on the scope and it is extremely flat topped, not to mention it is double sideband and sounds like crap.... The NPC-RC mod will flat top the crap out of the radio and any wattage increase will only be harmonics produced on bands you are nowhere near operating on.... No sense in have those extra watts if they don't make it onto the frequency your talking on.... Align the radio to spec, Adjust the AMC for a proper scope pattern, Set the carrier, and then you can tweak further.... You can achieve alot of extra on frequency power without disabling the limiter.... Need a scope.... Push the positives as far as you can without clipping it, run them to the ragged edge and be clean.... A radio that is flat topping will show big watts but they are bogus watts and a spectrum analyzer and scope will show ya that.... I have a radio here right now with the NPC-RC mod on it and I could post a pic of the scope to show what it looks like.... It's only cb radio and noone say's you have to sound good right???? It's your radio.... Either way, enjoy....

[freightliner06]

If you knew what you wanted to do then why did you ask???? Loud and clear doesn't mean that it sounds good.... It might sound good to truckers but to a decent station, not so good.... Hey, what do I know anyways!!!! I guess the piece of paper on my wall means nothing.... You obviously think you know more then us so your on your own and with that attitude you'll be lucky to get help from anyone in the future.... You say "who cares what it looks like on a scope" I'll tell you who, the people who have to deal with your unnecessary interference and having to listen to you come through every piece of equipment in their homes.... Enjoy....

[freightliner06]

I love these posts because they do a whole lot of talking and accomplish nothing.... It's filled with accusations, name calling, finger pointing and assumptions.... So since we are in the modifications section let's talk modifications shall we? The NPC-RC mod you speak of is intended for a low deadkey, one much lower then you would be using with that radio, something around 2 watts.... Now, the reason you need a scope and why it was suggested was because no matter what mod you use whether it be the NPC or a straight tune, it is still needed to achieve the proper results.... The NPC-RC mod requires the use of a scope in order to set it up properly or else it will be severely flat topped and the only thing you will be achieving is making your meter happy but do nothing for your signal.... A scope can see things that a watt meter can't and will never see and therefore allows you to tune aspects of the radio that you just can't do with a meter and a bag of screwdrivers.... A big/bigger carrier will not work properly with the NPC mod for this radio.... The mod you did is a simple swing mod and is in no way shape or form the NPC mod and it is completely non-linear.... I personally do not care for the NPC-RC mod but if done correctly it looks half way decent and will drive an amp nicely with at least some linearity to it.... I will give you one and only one hint towards the NPC and that is, you must use a 1n4001 and a 100 ohm resistor.... The idea behind it is to push the positive peaks to the absolute max and keep the negative peaks at or around 98% and this is where the scope is needed and where your bias needs to be adjusted.... The NPC mod is more then just adding a diode to the radio and talking on it.... People tried to tell you this and suggested taking it to a qualified tech but most got an arrogant response such as "I hope I live near you so I can ruin your day with it." This is a completely immature response and we do all know it is a cb radio forum and we do all know it's a mods section but there is more to modifying then just twisting pots and adding diodes.... Making modifications to your radio is supposed to be a learning experience and hopefully you will learn how your radio works and what everything does so you can further enjoy the hobby.... My experience and "piece of paper" IS revelant here and it is probably more relavant here then anywhere else.... The nickname is a joke and it was because of a radio I got from a guy with a 2006 freightliner.... The radio was a curse and badly, I mean badly hacked and cut up.... It took forever to get working properly and it's a long story.... I also drove truck to help put myself through college so I'm not opposed to anything "trucker." Trucker's like a certain type of audio that is typically not appealing to most, you know what I'm talking about.... Too much echo and way overmodulated.... If you were looking for power then a combo radio/amp vs. a radio and separate amp was not the way to go.... A separate radio and box configuration will always out talk the combo radio.... You said I was trolling a "radio mods" forum but I can't see how that is possible with over 150 posts.... I hardly call that trolling.... I'm not a ham operator nor did I ever say I was or state that modifications violate section blah blah blah of said ARRL handbook, this was purely an assumption.... I have a ton of fun with my radio collection but you need to understand that when people say to have your radio aligned and tuned that it is a necessary part of proper operation on 11 meter.... These export radios are built and set to run on 10 meter not 11 meter, so when you convert them they need to aligned so that the radio functions as it should on 11 meter and so it will actually receive well.... By having the radio aligned you will be maximizing it's potential now and in the future and any mods done later will have a much greater effect on a properly setup and tuned radio.... Look at it this way, you wouldn't run a 6 cylinder engine on 5 spark plugs so why run your radio with less then it's full potential.... People freeband and run illegal radios and noone cares we all know this.... If you want to punch through the muck then your wasting your time with that export radio.... A common misconception is that you have to have an export radio or your just not getting out but I'll tell ya what, go to a keydown and look around at the radios, you won't see many or any exports.... Harmonics make people happy and it makes cb shops tons of money with false wattage claims.... Here is an experiment, take your radio and hook up a TVI filter inline ( use a good quality one ) and then run it into a bird 43p attached to a dummyload and see how many watts come out.... You'll be surprised at the results.... A flat topping radio shows a ton of watts but none of it is on frequency and it is just wasted energy with the only benefit being a happy watt meter.... Half of the mods you listed can't and/or shouldn't be done without the proper equipment and being arrogant and stomping your feet isn't going to get the mods done right.... So, what type(s) of test equipment do you own???? How long have you been into radio???? What is your skill level when it comes to radio repair.... Can you solder well???? This info can help out alot....

[puddlejumper]

Thank you freightliner06. That alone was very informitive and well receved.

[freightliner06]

Thanks puddlejumper.... I'll have something else on the subject later as soon as I get to it....

[TheTeZ]

Yep, that's what I want. A loud, splatter-box radio. Hopefully I live near you so I can ruin your day with it.

...

than send it to RA, did an awesome job of turning mine into a splatter box, had to get it fixed.


anyway, I have a buncha radios, most of which sound awesome, my 3 main radios have all but put on both a scope and spectrum analyzer and my techs shop. The radios sound great, especially my 95t2 And you know what... its now on frequency no splatter, just had to take it to my tech get a few things fixed up, and its where it should be, and not all over the spectrum, I have never said this to anyone about my radios, because i dont really care about "Walking over" others, but im pretty positive my 95t2 will walk over, jump on and kick around yours..... now i know that sounded pretty rude, but thats not how i meant it. The reason i say it is all of my power is where its supposed to be, not all over the place, mine sounds very loud and very clear on ssb, never really touch am, so i wouldent know, but i would assume so.

What this post was meant to do, is just let you know their is no need to "Sacrifice" much when geetting the radio worked on, it can be dead on, where its supposed to be and still have the modifications to make it louder/clearer/more powerful, IF THEY ARE DONE RIGHT

[freightliner06]

I've been trying to say this all along.... I guess you don't need $20,000 plus worth of equipment when you have radioshack and rectifier diodes.... To go a step further, why bother with an electronics degree you only need a screwdriver and a dosy meter....

[TheTeZ]

freight, i wasnt disagreeing with you, i was giving my post for 479

wasnt sure which way you were going with that last responce

[freightliner06]

It was not intended for you Tez, I got ya....

This is a Galaxy 88HL with the NPC-RC mod with volted final.... 2 watt low carrier and 5 watt high carrier.... TR53 removed, R249 removed, a piece of wire run from C195 to top hole of TP7, and 1n4001 and 100ohm resistor added at C189 and the cap from C189 is across the diode and resistor combo on solder side.... The pattern does not get much better turning down the mic gain.... The radio shows about 35 watts PEP on the Bird 43p but it sounds like crap and as you can see it looks like it too.... How many of those 35 watts are fake and on another frequency???? Here's the pics....

2 watt carrier.... Flat topped
[ external image ]

5 watt carrier.... Flat topped again
[ external image ]

Bird 43p showing 35 watts PEP.... This is a 100 watt slug because I think I left the 50 watt at another location.... This is close enough.... This is a real Bird slug and not a CDI.... I'll provide pics if needed....
[ external image ]

Enjoy and more to ccome....

[freightliner06]

Here's the radio

The volting wire

TP7 removed.... I took the mirror board out so you could see it
[ external image ]

Diode and resistor combo in heat shrink.... I put a dab of white grease on top so you could see it....
[ external image ]

TR53 and R249 removed.... This I have never understood.... Why remove both, removing one does the same thing....
[ external image ]

This radio was not done by anyone here or any sponsor it was brought in from some place out of state.... Shop was in a truck stop somewhere.... Enjoy

[puddlejumper]

Freightliner06 you are obviously far more knowaledgeable when it comes to internal workings of a radio then I could ever hope to be.Just reading some of the things written on this site and looking at some of the set ups you guys come up with is amazing.I have just purchased a 94 hp and was hope to got some insite on what to or not to do with it and I believe you have done that.Thanks P/J

Don't they always say "a picture is worth a thousand words?" It speaks for itself, enough said.... Ultimately it's your equipment and your free to do as you wish just be prepared....

i've got a dosy and a whole mess of screwdrivers! i'm smarter than you!!!! lol

[BuzzSaw444]

I have a 95t2 that I can't use a power mic on, as it sqeals as soon as I turn it up slightly. I want to make it go back to normal. Where should I look on the board to reverse this 'overmodulation'? Whar is the transistor number for the limiter, as I want to put a replacement in if that is the problem.
What do you all think?

[freightliner06]

Check TR32, TR53, R249, D83 and I believe I have even seen D70 cut too... TR32 will make it squeal like a pig... That radio doesn't need a power mic BTW... If your running a stock radio then a power mic might be of use but not on a properly tuned unit... The transistor for TR32 and TR53 is a 2sc945... If your still having an issue with it PM me and we can work it out... I've repaired far too many of these hacked export radios done by these cheese balls who call themselves "Galaxy Radio Doctors" should be more like "surgeons."

[D Day]

Wow. Solicit pontification? LMFAO!! Hey 479tx I'm adding you as a friend. I've got a scope and all my teeth as well so this could get interesting. The rest of you guys need to lighten up a bit. Does it really make you that mad that some of us are actually talking worldwide on our 'splatter boxes' with no problems whatsoever and having fun doing it? And yes freightliner, no offence but you do sound like an uptight HAM with a vendetta. As far as your scope readings go, I'm sure they're accurate. That radio wasn't modded correctly that's all. He said he added a 1N4001 in series with R264 which will work fine with what he's trying to accomplish (lower deadkey with full swing). Can't wait for the replies on this one..

[freightliner06]

I'm not wasting my time... It's simple... I have no vendetta and I'm not a ham... Do as you will... If your "worldwide" then let's see it next time at the keydown, until then those who choose to talk trash and not back it up can continue to hide behind their keyboards... I expect each and everyone of you who trash talk and make posts such as the above to be in the top three at the next keydown... If everyone else is wrong then prove your way is better. It's that simple!!!! This will end all further debates. Good Day

[D Day]

OK let me get this straight.. You think that the reason most of us got into freeband radio is to have keydown contests with the rest of the 'good ole boy' network? So what exactly does that prove anyway? Sounds like an excuse to drink cheap beer and waste time and energy. No, I think most of us are here to COMMUNICATE over long distances without the use of government (corporate) regulated means. Arrrrrggghhh!!!

[freightliner06]

You can't communicate if the receiveing station can't understand what your saying. The key is "most" are here to communicate but alot are here to "drop the maul on the next guy." If you read through the forum you will find "most" want to communicate by talking over everyone else and just plain out be a nuisance. Run your splatter box and talk worldwide if you like but there is a point when your station is just annoying. Listen to the "supabowl" and tell me those radios sound good. I think not. So why is it that you can't sound good and be worldwide? Seems as though most operators feel as if they have to be way overmodulated and barely understandable to be heard. Why have an oscilloscope if your just going to overmodulate and clip and snip. That doesn't require special equipment to achieve. I prefer to talk to a station that sounds good over one that is overly loud.

[D Day]

I agree that most of the nonsense on the superbowl is unintelligible. I don't seem to have that problem for two reasons: One my mouth doesn't get in they way when I talk, and two I don't run a D104 cranked up to '10'. Like I've said in other posts, when the grid fails and it will, this argument wont matter anyway. WE will be the only ones communicating while the rest of the population is having a collective panic attack. If anyone at that point complains that they can't understand me, then it will be the same situation that it is now. They're obviously in my neighborhood and I don't need a radio to communicate with them anyway.

[electrotech]

very entertaining post's I have laughed my a** off at all the remarks and even teared up a little thanks everyone for making my day. ROFLMAO.

This is right on, I know its an old post but what the heck. Many mods out there really mess up the radio because the guy doing them has NO CLUE that he needs a scope to do it right. The NPC-RC mod for the Galaxy radios it a pretty good mod when tuned with a scope. I have this mod on my 55V and it works great, had it done over a decade ago. Once its set and tuned leave it be!!!! Trying to get more watts is just going to make the sound quality go way south!!! Many hackers out there just look at the meter and believe more watts on the Dosy must be better, RIGHT. Oh I forgot to mention that it drives a two pill and it only does 150-175 watts max. Nothing but compliments on the audio it makes. Its no power house but I have no problem shooting skip from my truck with it when its rolling.
